|Frames of Reference - Richard Leacock|
This PSSC film utilizes a fascinating set consisting of a rotating table and furniture occupying surprisingly unpredictable spots within the viewing area. The fine cinematography by Abraham Morochnik, and funny narration by University of Toronto professors Donald Ivey and Patterson Hume is a wonderful example of the fun a creative team of filmmakers can have with a subject that other, less imaginative types might find pedestrian.

|Franck-Hertz Experiment - EDC (Education Development Center)|
Professor Byron L Youtz uses a stream of electrons accelerated through mercury vapor to show that the kinetic energy of the electrons is transferred to the mercury atoms only in discrete packets of energy. Establishes the association of the quantum of energy with a line in the spectrum of mercury. Points out that the Frank-Hertz experiment was one of the earliest indications of the existence of internal energy states within the atom...

|Magnet Laboratory, A - Richard Leacock|
In the hands of another director, the inner-workings of a magnet laboratory could have caused a whole classroom to fall asleep of boredom. No so when Leacock was hired to produce this twenty-minute version of lab mayhem. Try this: six researchers in a lab at MIT in the late 1950's show-off the power of electro-magnets, and in the process, accidentally set an experiment on fire(Leacock says he did a retake without the fire, but preferred the immediacy of the fire sequence and kept it in)...
